Signal Processing For Dense Fields Of Miniature Impulsive Sources And Sonobuoy Receivers
Agency / Branch:
DOD / NAVY
The Navy requires a new modular signal processing architecture to host various candidate algorithms in support of the dense field of miniature sonobuoy concept. The dense field concept is in direct support of the N88 Air ASW Vision Statement which states that "continued pursuit of the miniaturization of sonobuoys, including the EER sources and receivers, is important for overcoming load restrictions and maximizing search area coverage and prosecution response flexibility." The SBIR solicitation cites several processing advantages that a dense field has over longer range systems. Improved ability to make environmental predictions, greater chance of multiple detections, and increased usable bandwidth are some of the primary advantages. The Navy is seeking a processing architecture that is modular to allow easy substitution and evaluation of algorithms intended to exploit these advantages. Our Phase 2 approach is to implement and evaluate the standard modular baseline impulsive signal processing architecture defined in Phase 1, using the RDA, Incorporated L-CAP system. This implementation is performed by way of incorporating three innovative algorithms designed in Phase 1. The modified L-CAP system will be used for supporting Navy testing of new sensors designed specifically for the dense field deployment concept.
